Heart Rate Zone Calculator

Calculate your personalized heart rate training zones with our research-based tool. Heart rate zone training helps optimize cardiovascular fitness, improve endurance, and maximize calorie burn during workouts. According to American Heart Association, training in specific heart rate zones can help you achieve your fitness goals more efficiently.

Calculate Your Heart Rate Zones

Your Heart Rate Zones

Based on a maximum heart rate of bpm and resting heart rate of bpm.

50-60%
Zone 1: Recovery
bpm
Very light intensity. Perfect for warm-up, cool-down, and active recovery between harder workouts.
60-70%
Zone 2: Endurance
bpm
Light intensity. Improves basic endurance and fat burning. Good for long, steady workouts.
70-80%
Zone 3: Aerobic
bpm
Moderate intensity. Improves aerobic fitness and efficiency. Challenging but sustainable pace.
80-90%
Zone 4: Threshold
bpm
Hard intensity. Increases lactate threshold and maximal performance. Challenging to maintain.
90-100%
Zone 5: Maximum
bpm
Maximum intensity. Develops maximum performance and speed. Short intervals only.

Why Use Heart Rate Zones?

Heart rate zone training allows you to optimize your workouts by targeting specific physiological adaptations. According to research, training at different intensities triggers different metabolic pathways and training adaptations. By matching your exercise intensity to your goals, you can make your workouts more effective and efficient.

Different Calculation Methods

While the basic formula (220 – age) has been widely used for decades, more accurate formulas like Karvonen and Tanaka may provide better results. The Karvonen formula accounts for your resting heart rate, creating more personalized zones that reflect your current fitness level. The Tanaka formula (208 – 0.7 × age) has been shown to be more accurate for older adults.

Zone Training Benefits

According to sports science research, zone training offers numerous benefits: improved cardiovascular health, better endurance, increased calorie burn efficiency, reduced injury risk, and more effective recovery. Different zones offer different benefits, from fat burning in lower zones to performance improvements in higher zones.

Finding Your Resting Heart Rate

For the most accurate measurement, take your pulse first thing in the morning before getting out of bed, ideally for 3-5 consecutive days. Count your heartbeats for 60 seconds, or count for 30 seconds and multiply by 2. The average of these readings will give you a reliable resting heart rate value for zone calculations.

EXPERT TIP: For optimal cardiovascular development, research suggests spending approximately 80% of your training time in Zones 1-2 (low intensity) and 20% in Zones 4-5 (high intensity). This polarized training approach has been shown to optimize fitness gains while minimizing injury risk and overtraining according to ACE Fitness research.
